Cutting multiple layers.

[Dave Monk]

The first time I cut two layers of 1/4 Baltic ply I pretty well covered a piece with double faces scotch tape and placed the second on it. When I got done I thought I would tear my projects up trying to get them apart. The project I am working on now I put 3 strips around the perimeter. It keeps trying to come apart. Any comments would be appreciated. dave

When I stack cut more than 2 pieces I use hot glue to hold them together.  I used to use wrap around tape.  Scotch tape is not a good tape for that.  The Blue Painters tape holds well and comes off without destroying the wood.  It does not leave tape glue residue like scotch tape or masking tape does.  Most clear packing tape will leave tape glue so if you want to tape the layers together I suggest the blue painters tape.

I wrap the edges with blue painters tape and a couple two or three brad nails in waste areas in the pattern.

I would echo everything above. I use a staple gun from the "top" and the "bottom" on 2 sides of the waste perimeter.

I just use brad nails in a bunch of the waste areas and this always holds it together nice and tight, just be sure to have at least two in the last waste area so it doesnt pivot

Dave, I use a glue gun and glue around the edges. I've never had any problems doing it this way, and if needed the glue is easy to remove.

I too use a hot glue gun if the project is being cut out from the inside of the stack. If I'm cutting portraits where the edges of the boards will be part of the project, I'll tape the edges with blue painters tape .

Me an Jerry are on the same page stapling!

I use a staple gun for stack 3-4 pieces. I use 3/8 staples . Staple board 1 to board 2 and board 3 po board 2 ect.Just staple where the blade dowsn't cu into a staple.. holds good.

I have used all the methods described. Now most of the time I use a quality double faced tape in small pieces in several locations around the perimeter and sometimes in the center area.   One thing I have found is making sure surfaces are dust free and applying allot of pressure to assure good tape adhesion makes all the difference.   To separate the stack after cutting I sometimes use a heat gun to loosen the tape adhesion. Works for me.

Owning a frame shop has some advantages.  We use double sided tape in all projects and it works great for stack cutting.  I just make sure it is placed in the waste area.

[WayneMahler]

I have used masking tape, but if the outside is going to be part of the cutting I switch to blue painters tape because of the glue issue. I have heard so many times about hot glue, I may have to try it.

I am another hot glue fan. I have tried all the other methods mentioned but hot glue works best for me.

Hot Glue..............

 

Tip:   rubbing alcohol removes hot glue.

I used to wrap stacks in tape, but these days I mostly use hot glue on the edges.  One tip I read some time ago suggested one could drill holes and drive round toothpicks into waste areas, like a brad.  Advantage being that the toothpick won't scratch your table.  Simply cut off the excess and sand flush.  I've never tried it, but seems like a neat idea.

I use 3 round toothpicks in a triangular pattern (you could use more or less) with a press fit in the waste areas. Then I wrap with clear packing tape. Never comes loose until you cut the area with the last toothpick. Works pretty well.
